INCUBUS, OR NIGHT-MARE.

“O’er ladies’ lips, who straight on kisses dream.”

ROMEO AND JULIET.

“Let us be lead within thy bosom, Richard,

And weigh thee down.”

KING RICHARD III.

ASTR. I will no longer hesitate to grant that the dream occurs in the

moment of departing or returning consciousness. Still, are you not

_reversing_ the order of these phenomena? may not the excitement of

vague ideas in the mind be, itself, the cause of waking, and not the

consequence of slumber, or half-sleep?

EV. I believe not, except the sensibility of the body be influenced by

touch, or sound, or by oppressive congestions of blood in the brain,

causing that state of disturbance which reduces sound sleep to slumber;

as in the instance of “Night-mare,” which is to the mind what sensation

is to the body, restoring it to a state of _half-consciousness_,

essential to that sort of dreaming, in which we make a painful effort to

relieve, and at last awake.

CAST. Mara, by my fay! the night-spectre of Scandinavia; that evil

spirit of the Runic theology, who weighed upon the bosom, and bereaved

her victims of speech and motion: that oppressive dream, therefore,

termed _Hag-ridden_, or, in the Anglo-Saxon, _Elf-siderme_. Is it not

she, of whom it is written,—

“We seem to run, and destitute of force,

Our sinking limbs forsake us in the course.

In vain we heave for breath, in vain we cry;

The nerves unbraced, their usual strength deny,

And on the tongue the faltering accents die.”

EV. A very faithful picture.

Sound sleep will often be broken by pain or uneasiness occurring in a

particular part of the body; the dream will then often bear an

instructive reference to the seat and nature of such pain. If cramp has

attacked any of the limbs, or the head has been long confined back, the

dream may be enlivened by some analogous tortures in the dungeon of the

Inquisition; and it is curious, that a waking wish for some relief from

unpleasant sensations will be _re_-excited in the dream,—a _dreamy

fulfilment_. Captain Back, during one of the Arctic expeditions, when

nearly in a state of starvation, often dreamed of indulging in _a

delicious repast_. And Professor Stewart thus writes,—“I have been told

by a friend, that, having occasion to apply a bottle of hot water to his

feet, he dreamed that he was making a journey to the top of Mount Ætna,

and that he found the heat of the ground insupportable. Another, having

a blister applied to the head, dreamed that he was _scalped_ by a party

of Indians.”

If on these occasions we are warm in bed, our dreams will be often

pleasing, and the scenes in the tropics; if _cold_, or chilly, the

reverse, and we shall believe ourselves in Zembla.

Holcroft had been musing on the probabilities of life and death, and one

night went in pain to bed. He dreamed his body was severed above his

hips, and again joined in a surprising manner. He was astonished to

think he was alive, and afraid of being struck, lest the parts should be

dissevered.

Tempests heard in a slumber will be often associated with a dream of

shipwreck; and some persons will dream of their having given pain to, or

injured, others: they wake, and find some close analogy to _their own_

sensations.

It is recorded that Cornelius Rufus dreamed that he was blind, and _so_

indeed _he awoke_.

In other cases, we have the _double touch_, as it is termed; dreams of

forcible detention occur, and the sleeper has found that he had with one

hand tightly grasped the other. If this hand had been _moved in sleep_

unconsciously, the dream, no doubt, would have been essentially changed.

And thus we have all the phenomena realised, which Shakspere has

referred to in the visitations of his incorrigible Mab.

Elliston was always awaked by nightmare when sleeping in a strange bed.

As in some persons, by submitting the body to certain impressions during

sleep, associated dreams may be produced at pleasure; so if the body or

legs hang over the side of a bed, we may instantly dream of falling from

a precipice: and it is curious that, under these illusions, we awake

when we are past hope and our despair is at its height: in falling, at

the moment we are about to be dashed to atoms; and, in drowning, when

the last bubbles are gurgling in the throat.

When we read in the Bodleian, Astrophel, I will point you to other

curious experiments of this sort, by M. de Buzareingries.

Sounds also may be partly associated with the dream at waking, and with

reality, when awake. Under this illusive impression, even murder has

been _innocently_ committed, on one, who waked, and stabbed his brother

at the moment he was _dreaming_ of assassins.

CAST. And so may be explained, I suppose, this funny anecdote. A young

lover was drooping into a day-dream, while sitting with his brothers and

sisters, and his thought had turned on the cruelty of his mistress. He

was for a moment dreaming of her, when pussy, stretching her paws,

scratched his leg with a claw: there was an instant association, I

presume, of the wound with the lady’s cruelty, for he started and

exclaimed, “Oh Arabella, don’t!”

EV. Hippocrates quaintly alludes to the dreaming about seas and lakes as

an indication of _hydrothorax_; and to others, as symptomatic of

_effusion on the brain_: and it has been asserted, that gloomy dreams in

fevers indicate danger. But all this is hypothesis; indeed, the

delirious dreams of fever are often bright and cheerful.

The “Opium-Eater” has a strange fancy regarding his dreams of “silvery

expanses of water;” “these haunted me so much, that I feared that some

dropsical state or tendency of the brain, might thus be making itself

_objective_, and the sentient organ project itself as its own object.” I

hope you understand this, Astrophel—I do not.

In the morbid condition of _hypochondriasis_, which is a sort of

permanent _daymare_, similar fancies are excited. Esquirol’s patient at

Notre Dame thought the pope held council in her belly;—her intestines

were found _closely adherent_ together. Another monomaniac thought the

devil had stretched a cord across her stomach;—her heart was _adherent

to its bag_. Another believed that her body was stolen by the

devil;—she was in reality paralytic, and _insensible_ to blows or

pricking.

To explain some of these illusions, Jason Pratensis very gravely

asserts, that “the devil being a slender incomprehensible spirit, can

easily insinuate and wind himself into human bodies, and, cunningly

couched in our bowels, terrify our souls with fearful dreams.”

I may add that we see, in some, a delirious _transmigration of

sensation_. Parkinson relates these cases. One referred his own

sensation to others, telling his nurse that his visitors were hungry,

while his own voracity plainly indicated that the _hunger was in

himself_. Another, in a fit of intoxication, insisted on undressing all

his family, as they were drunk, and could not do it themselves.

Now we certainly move ourselves unconsciously in our sleep as a relief

from painful positions. If, however, these uneasy sensations are

increased from stagnant blood about the heart and lungs, the oppression

is extreme, and _loads_ the moving powers; producing a transient agony

and an intense effort. If this were unsuccessful on the limbs and

speech, the result would be often destructive.

The night-mare dreamers are usually lethargic, and their ideas are often

wild and visionary.

Polidori, the author of the “Vampire,” was a prey to night-mare; he died

with a laudanum bottle in his bed. And Coleridge might have thus left a

sad and pointed moral; blazoning his wretched suicide to that world,

which unconsciously has pored with a thrill of admiration over those

fruits of his delinquency, the romantic and unearthly stories of

Christabel and the Ancient Mariner.

The grand feature of night-mare, then, is _impediment_: but how can I

record all its varieties of miserable struggles; of attacks and

manglings from wild monsters: of the rolling of mountains on the heart:

or the unhallowed embraces of a witch?

The young lady who reads mythology, will fancy herself a syrinx, and

struggle to escape from the amorous clutches of Pan. If we have been

thinking of Chamouni and her giant peaks of snow, we may be overwhelmed

in our sleep by the fall of an avalanche; or we may be dashed off a

precipice, and feel ourselves falling into interminable space without a

hope of resting.

A lady whom I know, and who is a frequent subject of night-mare, is very

uniform in this dreamy occupation. She is shaken to and fro in her bed

by fiends, and the process seems to her to occupy considerable time. And

there are many who are tortured by the feeling that they are buried

alive, and attempt to cry out, and beat against their coffin-lid in

vain. Aurelian writes, that the epidemics in Rome were premonished by

_incubus_.

These, and thousands of a similar kind, might be cited; but a vivid

imagination, with a hint or two, will readily create them at its

pleasure.

“A battalion of French soldiers, during the toils and dangers of a

campaign, were marching on a certain point on a most oppressive day, and

at double the usual speed; their strength was eight hundred men, all

hardy, seasoned, and courageous; careless of danger, despising the

devil, and little occupied with the thoughts of ghosts and

phantasmagoria. On the night of the occurrence in question, the

battalion was forced to occupy a narrow and low building at Tropœa,

barely calculated to accommodate three hundred persons. Nevertheless,

they slept; but, at midnight, one and all were roused by frightful

screams issuing from all quarters of the house; and to the eyes of the

astonished and affrighted soldiers appeared the vision of a huge dog,

which bounded in through the window, and rushed with extraordinary

heaviness and speed over the breasts of the spectators. The soldiers

quitted the building in terror. Next night, by the solicitations of the

surgeon and _chef-de-bataillon_, who accompanied them, they again

resumed their previous quarters. ‘We saw,’ says the narrator, ‘that they

_slept_. We watched the arrival of the hour of the preceding panic, and

midnight had scarcely struck when the veteran soldiers, for the second

time, started to their feet. Again they had heard the supernatural

voices, again the visionary hound had bestrode them to suffocation. The

_chef-de-bataillon_ and myself heard or saw nothing of these events.’”

The superstitious thought this spectre to be the devil; but the heat and

_carbonic acid gas_ were, I believe, enough for the excitement of the

phantasm and the feeling.

There can scarcely be imagined a more terrific feeling than this sense

of extreme danger, or difficulty, this intense impediment, without a

power to avert it. The constant labour of Sisyphus, with his

rolling-down stone, and the punishment of Tantalus, would yield in

severity to the agony of night-mare, but for its _transient_ existence.

It seems to me, that this want of balance between will and power

influences human nature so much, that life itself may be termed one long

and painful _incubus_. The actions we perform seldom reach the

perfection which the will desires. Hence arises that constant

dissatisfaction, which even the close approach to perfection of some of

the most accomplished professors of art and science cannot avert.

We must confess, with Socrates, that the extent of our knowledge is

indeed but a conviction of our ignorance. The metaphor of Sir Isaac

Newton, on the insignificance of his own scientific attainments, is well

known. Sir Joshua Reynolds so highly appreciated perfection in his art,

that he was ever discontented with his own paintings; and frequently, as

I have heard, by repeated touches, destroyed the effect of a picture,

which had been in its early stages beautiful. And Dr. Johnson, after

astonishing the world with his perfect specimen of lexicographical

composition, confessed that he “had not satisfied his own expectations.”

May I add to these the frequent _discontent_ of the unrivalled Paganini?

IDA. The desire of the mind is, indeed, unlimited; and when this is

intense, it wishes to appropriate to itself all which it can

_comprehend_. But disappointment _must_ ensue; for all wish to be the

whole, when they form but a part. Thus will ever be proved the futility

of _worldly_ ambition,—it is never satisfied. But the desires of

religion are not a phantom, or an incubus. True devotion, which aspires

to heaven, as the hart panteth for the water-brooks, will never fail.

Its fervent hopes and devout prayers, we believe, will be blessed by

their accomplishment.

CAST. Then the visitations of the incomparable Mab are nought but the

infliction of the night-mare? Gentle Master Evelyn, how should I be

aweary of your philosophy, but that I am half won over to believe it

true? In good faith,

“The Gordian knot of it you do unloose

Familiar as your garter.”

EV. Then, I pray you, let me counsel you not to court such visits, dear

Castaly. There is some peril in the touch both of Mab and Mara; for

although rare and transient cases of night-mare excite no alarm, yet its

repetition, in a severe form, is not to be slighted. It sometimes has

been the forerunner of _epilepsy_; its immediate cause being obstruction

to the course of the blood by which the brain especially is surcharged,

and the action of the lungs and heart impeded, as we prove by the

extreme labour of breathing at the time we awake.

I believe that there is usually a fulness of blood, also, in the vessels

of the spinal marrow; as, although nightmare may occur in the _sitting_,

it is far more frequent in the _recumbent_ position. Thus the marrow is

oppressed, and there is then no force transmitted by the nerves to put

the muscles into action.

Distention of the stomach should be prevented, as the _diaphragm_ is

thus pushed up against the lungs, and the gas is accumulated in the

cavity. All these conditions often occur in our waking moods, but _then_

our judgment tells us how to relieve them speedily; whereas, _in sleep_,

the load accumulates. All indigestible substances, therefore, should be

avoided, as nuts, cucumbers, shell-fish, &c.

Early and light suppers we advise to those whom Madame Mara so

unmercifully overlies. A mattress should be our couch, and we should

endeavour to compose ourselves _on one side_, having, previous to our

rest, taken _gentle exercise_.
